Question 226593: i need your help on writing (y-5=1/3(x-6)
y-5 = 1/3x - 2
bring the -5 to the other side
becomes
y= 1/3x-2+5 ---> y = 1/3x + 3

Question 226647: what is the slope and y intercept of the graph of 5x-2y=30?
you need to write this in terms of y :
5x-2y = 30
bringing 5x to the other side becomes -2y = 30 - 5x
dividing by -2 becomes y = 30/-2 -5x/-2
arrage it becomes y = 5x/2 -15
looking at the equestion we can find the slope and y intercept
slope = 5x/2 , y-int = -15
good luck
